Unhealthy air advisory in Bay Area due to Oregon wildfires

Smoke from wildfires burning in Oregon drifted across the Bay Area on Monday, prompting air quality officials to issue a health advisory for the region.

The Bay Area Air Quality Management District urged the public to limit their exposure to smoke by staying indoors if possible with windows and doors closed, and setting air conditioners and car vents to recirculate. People with asthma should follow their doctors' directions about taking medicine.

Smoke from the Oregon wildfires created unhealthy concentrations of fine particle pollution in much of the Bay Area on Monday, with the worst air quality along the coast and central Bay Area.

The smoke concentrations are expected to diminish Tuesday to fall within public health standards, according to the air district.

More than 125,000 acres of wild lands were burning Monday in Oregon and Washington.
